VpCI® Additives for Lubricants and Greases

This full line of additives offers versatile corrosion inhibitor packages for both solvent- and oil-based lube and grease systems. A common misconception is that oil-based products are naturally strong rust preventatives. While oil itself can help displace moisture, a good corrosion inhibiting additive can significantly increase protection of lube and grease systems. Many of these additives offer vapor phase protection for metals in the void space above the lubricant.

  • M-168: Solvent-based additive especially effective for preventing salt corrosion attacks. Package: 5 gallon (19 liter) containers, 55 gallon (208 liter) metal drums, liquid totes, and bulk.
  • M-236: For corrosion protection of yellow metals in contact with oil-based systems, such as transformer oil. Package: 5 gallon (19 liter) pails, 55 gallon (208 liter) drums, liquid totes, and bulk. 
  • M-238: Effective vapor and contact corrosion inhibitor for a variety of oil- and solvent-based systems. Package: 5 gallon (19 liter) pails, 55 gallon (208 liter) drums, liquid totes, and bulk.
  • M-320: Provides vapor and contact protection to oil systems such as gearboxes. Recommended during layup. Package: 5 gallon (19 liter) pails, 55 gallon (208 liter) drums, liquid totes, and bulk.
